invii PERCIVAL HAMMER TROUTMAN, OF OAION CITY, COLORADO,

ORCHARD-HEATER.

To all whom it may concern:

Be it known that I, PnncivAL HAMMER TnoU'rMAN, a citizen of the United States, residing at Canon City, county of Fremont, and State of Colorado, have invented certain new and useful Improvements in Orchard- I-Ieaters; and I do declare the following to be aV full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in orchard heating devices, my object being t0 provide an attachment for the liquid fuel receptacle of an orchard heating device, whereby the burning of the fuel may be regulated and controlled.

Where my improved device is employed,

the receptacle may be made of the maximum capacity. TWhere it is required to burn fuel rapidly, the attachment will not be used, but where the burning capacity of a relatively arge receptacle is greater than desired in any particular instance, my improved attachment is applied, whereby the rapidity with which the fuel burns is lessened, owing to the reduced fuel surface exposed to the ire.

My improved attachment consists of rim engaging the upper edge of the receptacle, extending horizontally inward, whereby the top opening is reduced in size, the said rim having a depending member, extendin downwardly into the liquid fuel, when t e receptacle is full or approximately filled with fuel. This depending member may be of any desired length. However after the fuel is burned below the depending member the available burning surface of the liquid is virtually diminished to harmonize with thecircle described by the said member, since the outer portion of the fuel receptacle is closed at the top, thus preventing direct upward draft. In other words the diminished draft diminishes the burning .capacity of the device, thus limiting the amount of fuel consumed within a given time.

Having briefly outlined my improved construction, I will proceed to describe the same in detail, reference being made to the above drawing in which is illustrated an embodiment tlireof.

a top Specification of Letters Patent.

Application filed July 1G, 13u13.

Patented Nov. 15, 1910. semina. 5cc/,010.

In this drawing: Figure l is a perspective view of an orchard heating device, equipped with my improved attachment, the latter being partly broken away at the top. Fig. 2. is a central vertical section of the same. Fig. 3. is a perspective view of the attachment shown in detail.

The same reference characters indicate the same parts in all the views.

Let the numeral 5 designate the body of a receptacle adapted to hold liquid fuel. As shown in the drawing, this receptacle is largest at the top and slopes gradually toward the lower extremity, where it is smallest. The bottom 6, of the receptacle, has a central opening 7, surrounded by a centrally located upwardly projecting tube or chimney S. which is largest at the bottom and diminishes gradually toward its upper extremity.

Near the top of the chimney openings 9, are preferably formed. The body 5 of the receptacle, is mounted on a depending cylindrical support l0, having a draft opening l2. Vhile this form of orchard heater is well adapted to utilize my improvement, it is evident that the latter may be advantageously employed with any ordinary receptacle adapted to hold liquid fuel, when it is desired to diminish its burning capacity.

I't often becomes necessary to vary the heating capacity of these devices. For instance in fruit sections, the owners have heating devices distributed through the orchards and other localities to be protected from the frost, the number of devices employed being those required in the case of a sudden and relatively low fall in the temperature. In other words, the ordinary equipment must be sufficient to protect these localities in the event of a maximum fall in temperature, within a comparatively short time.

Now in the event that the fall is not s0 great, but still sutlicient to require some protection, my improved attachment will be available, and it is only necessary to simply set it on the device, the rim of the attachmentresting upon the upper edge of the receptacle, while the depending member extends downward thereinto, preferably entering the liquid fuel when the receptacle is full or approximately full.

Specifically my improved attachment as illustrated in the drawing, consists of a horizontal circulaipart 13, whose outer edge is bent downwardly as shown at 14, forming a flange for retaining the attachment in place upon the receptacle. The lower extremity of this retaining flange is normally of slightly less circumference than the outer circumference of the bead 15, surrounding the upper edge of the receptacle 5, whereby it is necessary to exert some pressure upon the attachment in order that its retaining flange may be sprung outwardly slightly, while passing the greatest circumference of the bead, after which the lower edge of the flange springs into place below the bead holding the attachment securely in place thereon.

At the inner edge of the part 13, is located the depending member 16, which may be of any desired length, preferably extending below the surface of the liquid when the receptacle is full, thereby reducing the surface area of the liquid exposed to the air, and consequently reducing the burning capacity of the device.

From the foregoing description the use of my improved device will be readily understood, and need not be further described in detail.

Having thus described my invention, what `I claim is:

1. The combination with a liquid fuel receptacle, of an open ended chimney for feeding air to the surface of the liquid fuel, an attachment for reducing the surface area of the liquid exposed to the atmosphere, and consisting of a removable device engaging the outer edge of the receptacle, extending inwardly partially closing the top of the receptacle, and having a depending annular member, extending into the receptacle a suitable distance for the purpose set forth.

2. The combination with an orchard heater including a receptacle for liquid fuel, of an open ended chimney for feeding air to the surface of the liquid fuel extending cen trally through the receptacle, a removable attachment adapted to rest upon the outer edge of the receptacle,partially closing the top of the receptacle, and having an an-` nular depending member of suitable length extending into the receptacle, for reducing the surface area of the liquid exposed to the atmosphere, substantially as described.

3. The combination with an orchard heater including a liquid fuel receptacle, an open ended chimney for feeding air to the surface of the liquid fuel, a circumferential bead at the top of the receptacle, and a removable attachment having a flange adapted to yield sufficiently to slip over the bead for retaining purposes, the said attachment being supported upon the upper edge of the receptacle extending into the latter partially closing the top thereof, and having a depending annular member extending downwardly into the receptacle for reducing the surface area of the liquid exposed to the atmosphere, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
